A sequence of mechanically selected random numbers given by Cox. These numbers in turn were taken (with permission) from a larger table by Kendall and Smith. In Cox, all numbers were given as pairs of digits. Here leading zeros have been lost, so, for example, where we have a(21)=6 the original list has 06. - Sean A. Irvine, Feb 28 2021

From Simon Howard, Oct 25 2024: (Start)
The same table of numbers is also used in earlier games by id Software, including Catacomb 3D (1991) and Wolfenstein 3D (1992), but was used as early as the Commander Keen series. Due to code reuse, the table subsequently found its way into games from other companies: Apogee Software's Rise of the Triad (1995) and Raven Software's Heretic (1994) and Hexen (1995) among others.
The sequence is bytes from a 32-bit linear congruential generator using a multiplier of 134775813 and an increment of 1; these parameters were used in the pseudorandom number generators shipped with various compilers produced by Borland International, Inc. in the late 1980s. This suggests that a program built using one of these compilers was used to generate the table. (End)
