FUNCTION : cuspsetinequiv1 - determine Gamma[1](N)-inequivalence of given set of cusps CALLING SEQUENCE : cuspsetinequiv1(cset,N) PARAMETERS : cset - set of cusps N - positive integer GLOBAL VARIABLES: equivpairs SYNOPSIS : Determines whether the cusps in in cset are Gamma[1](N)-inequivalent. This proc returns true or false. If equivalent pairs are found they are stored in the global variable equivpairs. EXAMPLES : DISCUSSION : SEE ALSO :
