Presentation

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

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

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

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