Definition
For independent standard normal variables $Z_1,\ldots,Z_k$ and an independent $V\sim\chi^2_\nu$, this table gives the lower-tail quantile $q_{k,\nu,p}=\inf\{x:\Pr(Q_{k,\nu}\leq x)\geq p\}$ of the studentized range $Q_{k,\nu}=(\max_i Z_i-\min_i Z_i)/\sqrt{V/\nu}$ [1].
Parameters
$\nu$
—   degrees of freedom ($\nu$ is a positive integer)
$k$
—   number of means ($k$ is an integer with $k\geq2$)
$p$
—   lower-tail probability ($0<p<1$)
Formulas
(1)
Write $G_{k,\nu}(x)=\Pr(Q_{k,\nu}\leq x)$. For $x>0$, $G_{2,\nu}(x)=I_{x^2/(2\nu+x^2)}(1/2,\nu/2)$. Here $B(z;a,b)$ is the incomplete beta function and $I_z(a,b)=B(z;a,b)/B(a,b)$ is its regularized form [4].
(2)
In terms of Quantiles of Student's $t$-distribution, $q_{2,\nu,p}=\sqrt{2}\,t_{\nu,(1+p)/2}$.
(3)
For $0<\alpha<1$, $q_{2,\nu,1-\alpha}=\sqrt{2}\,t_{\nu,1-\alpha/2}$, and $\Pr\{|T_\nu|>q_{2,\nu,1-\alpha}/\sqrt{2}\}=\alpha$. Here $T_\nu$ has the central Student distribution.
(4)
For $x>0$, $G_{3,\nu}(x)=1-\frac{6}{\pi}\int_0^{\pi/6}\left(1+\frac{x^2}{2\nu\cos^2\theta}\right)^{-\nu/2}\,\mathrm{d}\theta$. This follows by projecting three independent standard normals onto the plane perpendicular to $(1,1,1)$ and using polar coordinates; the derivation is in the attached mathematical notes.
(5)
$G_{k,\nu}(q_{k,\nu,p})=p$ and $1-G_{k,\nu}(q_{k,\nu,1-\alpha})=\alpha$ for $0<p,\alpha<1$. If $Q^{\mathrm{upper}}_{k,\nu}(\alpha)$ denotes the upper-tail critical value satisfying $\Pr(Q_{k,\nu}>Q^{\mathrm{upper}}_{k,\nu}(\alpha))=\alpha$, then $q_{k,\nu,p}=Q^{\mathrm{upper}}_{k,\nu}(1-p)$.
(6)
For one degree of freedom, $q_{2,1,p}=\sqrt{2}\tan(\pi p/2)$ and $q_{3,1,p}=\sqrt{\frac{1}{2\sin^2(\pi(1-p)/6)}-2}$.
(7)
For two means and two degrees of freedom, $q_{2,2,p}=2p/\sqrt{1-p^2}$.
Comments
(8)
The quantiles use the lower-tail probability convention. In particular, $p=19/20$ and $p=99/100$ correspond to the upper-tail significance levels $0.05$ and $0.01$ used in [3].
(9)
The range includes differences in both directions. Its level-$\alpha$ threshold is $q_{k,\nu,1-\alpha}$; the conversion to the two-sided Student threshold when $k=2$ is given in (3).
(10)
The stored rows cover two and three means. Two means gives the ordinary absolute Student comparison, while three means is the first nontrivial simultaneous comparison. The distribution itself is defined for every integer $k\geq2$.
(11)
The denominator is an independent estimate of the normal standard deviation. It is not the sample standard deviation of the same $Z_1,\ldots,Z_k$. The single-range convention agrees with nranges=1 in [1].
(12)
The probabilities $p$ are exact rationals in lowest terms. Their selection includes the median, the quartiles, conventional significance levels and their complements, and the upper $0.1\%$ critical value.

Data properties
Entries are of type: real number
digits: 100 (Unknown key)
Table is complete: no (it holds every combination of $k\in\{2,3\}$, $\nu\in\{1,2,\ldots,10,20\}$ and $p\in\{1/200,1/100,1/40,1/20,1/10,1/4,1/2,3/4,9/10,19/20,39/40,99/100,199/200,999/1000\}$, giving 308 entries. The degrees of freedom select small samples and a reference row at $\nu=20$ from [3]; the probabilities cover the median, quartiles and conventional significance thresholds. The two- and three-mean cases provide the ordinary absolute Student comparison and the first nontrivial simultaneous comparison)
How they were obtained:

Each quantile is enclosed by exact rational endpoints. Numerical quadrature at 135 decimal digits proposes a bracket, and 525-bit Arb arithmetic certifies strict CDF signs at both endpoints. For two means the CDF uses the regularized incomplete beta function. For three means a convergent power series for (4) carries an explicit Cauchy remainder bound; the derivation and bound are in the attached mathematical notes. The returned ball contains the entire bracket of width $4\cdot10^{-115}$. Every returned ball retained at least 374 bits of relative accuracy before rounding to 100 significant digits.

The independent checker uses finite elementary integration recurrences in 2048-bit ball arithmetic. It checks opposite CDF signs at the two endpoints represented by every stored decimal, rejects 308 deliberately shifted intervals, checks 42 closed-form rows, and checks strict ordering in probability and in the number of means. Four controls precede these comparisons. SciPy evaluates the general distribution on all 308 entries, with maximum CDF discrepancy $1.82\cdot10^{-13}$. Of 44 shared printed values in [3], 43 agree within half a last-place unit; the remaining printed value is discussed in its entry comment. All 44 agree within one printed unit. The generator, independent checker, source comparisons and numerical evidence are attached.

parameter selection: The degrees of freedom are $\nu=1,2,\ldots,10,20$, a small-sample subset of the reference rows in [3]. The probabilities use the family convention for statistical quantiles. Degrees of freedom $\nu\geq30$, larger numbers of means and the infinite-degree-of-freedom limit are outside the computed selection. (Unknown key)
