The GAP Bibliography currently contains 2217 records. Among others, it contains 1961 journal publication (the rest are books, PhD theses, preprints, etc.). These journal publications represent 331 journal, but almost a half of them (1042 papers) are published in the following 20 journals:

- J. Algebra :
**258** - Comm. Algebra:
**137** - J. Symbolic Comput.:
**88** - (*) Discrete Math.:
**66** - (*) Experiment. Math.:
**42** - J. Group Theory:
**41** - Internat. J. Algebra Comput.:
**41** - (*) European J. Combin.:
**38** - (*?) LMS J. Comput. Math.:
**37** - (*) J. Pure Appl. Algebra:
**37** - J. Algebra Appl.:
**36** - (*) Des. Codes Cryptogr.:
**35** - Arch. Math. (Basel):
**33** - Math. Comp.:
**26** - (*) J. Combin. Theory Ser. A:
**25** - Electron. J. Combin.:
**25** - Israel J. Math.:
**22** - J. Combin. Des.:
**20** - J. Algebraic Combin.:
**18** - Adv. Math.:
**17**

It’s interesting, however, which of these journals suggest publishing code together with the paper? I have marked with (*) journals where the guidelines for authors (click on the journal title to see them) at least mention an opportunity to submit supplementary material, though the wording used may be quite different. For example, Elsevier’s Discrete Math., European Journal of Combinatorics, J. Pure Appl. Algebra, J. Combin. Theory (Ser.A) and Advances in Mathematics all say *“Supplementary files offer the author additional possibilities to publish supporting applications, high-resolution images, background datasets, sound clips and more”*, so the code could go under *“more”. *Experimental Mathematics is more explicit in suggesting that “*detailed code can be submitted as a computer supplement”.*

There is no information available at the moment for the LMS Journal of Computation and Mathematics, which is currently closed for new submissions, awaiting for the LMS Special General Meeting tomorrow, but there were some in the past. You may see an example how they worked in the paper by Meinolf Geck linked from “In which journals should I publish my software” post by Neil Chue Hong of the Software Sustainability Institute.

Finally, Designs, Codes and Cryptography accepts *“electronic multimedia files (animations, movies, audio, etc.) and other supplementary files to be published online along with an article or a book chapter”*. In particular, it says that *“specialized format such as .pdb (chemical), .wrl (VRML), .nb (Mathematica notebook), and .tex can also be supplied”.*

I haven’t discovered suggestions to submit the code in other journals from the list above. I am happy to be corrected in case I’ve overlooked them, but in this case other authors could probably overlook them too…
