Presentation

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

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

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

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