Rigorous Maass forms were computed by Kieran Child, Andrei Seymour-Howell, and David Lowry-Duda. The algorithms are based on ideas of Stark [MR:0803370] and Hejhal [MR:1106989] and described further in [arXiv:2204.11761] and [MR:4493409].
Heuristic Maass forms were computed by Fredrik Strömberg, Stefan Lemurell, Holger Then, and David Farmer. Details can be found in [MR:2429890], [MR:2895234], [MR:2164106], and [arXiv:math/0506102].

Initial page design and coding by Stefan Lemurell and Fredrik Strömberg. Later updates were made by David Lowry-Duda.
The code and ideas leading to rigorous Maass forms rely heavily on the work of Min Lee, Andrew Booker, and Andreas Strömbergsson.
