Presentation

minimal degreeμ(G) = 45
transitive degreeμt(G) = 3135

A minimal faithful permutation representation — 2 generators on 45 points:

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