/* gpmult2.c 25/11/94.
* 8 / 10 / 98 large - scale re - organisation .
* Calculates a multiplier automaton of a short - lex automatic group ,
* for a word in the generators of length 2 , using the length - 2
* general multiplier .
* This program assumes that kbprog with - wd option , gpwa , gpgenmult
* gpgenmult2 and preferably gpcheckmult have already been run of G .
*
* SYNOPSIS :
* gpmult2 [ - ip d / s ] [ - op d / s ] [ - silent ] [ - v ] [ - l / - h ] g1 g2 groupname
*
* Input is from groupname . gm2 ( and possibly groupname . gm2_ut ) .
* and individual 2 - generator multipliers to groupname . mult_g1_g2 ,
* where g1 and g2 are the generator numbers .
*
* OPTIONS :
* - ip d / s input in dense or sparse format - sparse is default
* - op d / s output in dense or sparse format - sparse is default
* - v verbose
* - silent no diagnostics
* - l / - h large / huge hash - tables ( for big examples )
