Presentation

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

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

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

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