Supplementary material:

There are two web pages containing supplementary material for the book, one at the Fields Institute and one at the AMS, but they are outdated. Please use the material below instead.

Material for further experiments:

Using William A. Stein's package HECKE (included in the MAGMA computer algebra system) I computed Fourier coefficients of newforms for \Gamma_0(N) with rational coefficients for certain weights. Each row of the tables contains a level and the coefficients of a certain newform of this level for the first 25 primes (2 to 97).

Back in the early 1990s, using Omikron Basic 3.5 and the corresponding compiler, I wrote the car race game GPPO (or GPPD, in an earlier version) for Atari ST(E) systems. It requires 640x400 b/w resolution (I think it probably was the only car race game available for us SM124 users). It will run, for example, under the Steem Atari STE emulator.
