Presentation

minimal degreeμ(G) = 55
transitive degreeμt(G) = 2432

A minimal faithful permutation representation — 4 generators on 55 points:

(1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19)(21,23)(24,25)(26,34)(27,38)(28,43)(29,31)(30,35)(32,41)(33,40)(36,54)(37,51)(39,49)(42,50)(44,48)(45,53)(46,55)(47,52);(20,21,22,23);(24,26,29,37)(25,30,31,45)(27,39,42,55)(28,44,40,36)(32,48,47,54)(33,49,43,46)(34,50,51,38)(35,52,53,41);(25,31)(30,45)(32,47)(33,43)(34,51)(38,50)(46,49)(48,54)
