gnu(31920)=6851

[grouptheoryenthusiast]

Please check that you provide the following details when submitting new values of Gnu(n):

• Version of GAP and critical packages: GrpConst, Cubefree, etc.
• Brief description of the computer used for the calculation (operating system, processor, RAM)
• Runtime required for the calculation
• GAP commands used for the calculation
• Confirm that the output r of ConstructAllGroups is a list of groups (ForAll(r,IsGroup) should return true), otherwise confirm that if the output contained lists of groups, then those groups were also shown to be pairwise non-isomorphic.

Thank you for submitting new gnu(n). We will recalculate it and add to the database if we get the same result.

Checklist for the reviewer:

• checked and assigned labels "new (n<50000)" or "recomputation", if needed
• set "replication needed" label (unless it starts immediately)
• changed it to "replication in progress" label when the replication has been started
• changed it to "replicated" after successful replication review
• reproducible value of gnu(n)
• no essential runtime differences
• sufficient level of technical details

Checklist for the maintainer:

• correct arguments of command to store data
• correct location of new line in the data file
• mention submitter and reviewer in the commit message
• Close corresponding issue from the commit message
