Presentation

minimal degreeμ(G) = 26
transitive degreeμt(G) = 256

A minimal faithful permutation representation — 6 generators on 26 points:

(19,20)(21,23)(22,24)(25,26);(4,6)(7,8,9,10)(11,12)(13,17)(14,16)(15,18)(19,20,22,24)(21,25,26,23);(3,4)(5,6)(7,8)(9,10)(11,12,14,16)(13,15,18,17)(19,20)(21,23)(22,24)(25,26);(4,6)(8,10)(11,12)(13,15)(14,16)(17,18)(19,20)(21,25)(22,24)(23,26);(3,4)(5,6)(7,8)(9,10)(11,13,14,18)(12,15,16,17)(19,21)(20,23)(22,26)(24,25);(1,2)

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