Presentation

minimal degreeμ(G) = 26
transitive degreeμt(G) = 128

A minimal faithful permutation representation — 7 generators on 26 points:

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

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