Presentation

minimal degreeμ(G) = 42
transitive degreeμt(G) = 256

A minimal faithful permutation representation — 5 generators on 42 points:

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

Past the SmallGroups library coverage — no SmallGroups id. Construct it from a minimal faithful permutation representation:
