This is the accompanying worksheet for the paper
"Enumeration of Non-oriented maps via integrability"
 

This worksheet contains:
A - an implementation of the explicit recurrences of the paper in the form of ready to run programs.
B - automated calculations of the non-shifted ODEs stated in non-explicit form in the paper, and recursive programs obtained from them to compute the numbers
C - some sanity checks against already known sequences (small genus, one face, ...)
D -
explicit displays of the big ODEs if you are into this
E -
some tables
