Andrew Howroyd: 10000 terms would have been enough, 40000 is a little excessive.

Stig Blücher Brink: The solutions to the general birthday problem for very large numbers is a difficult challenge in real world scenarios, see e.g.: https://www.ism.ac.jp/editsec/aism/pdf/044_3_0479.pdf

Jon E. Schoenfield: Can the b-file be shortened to 10000 terms?
23:59
