Presentation

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

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

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

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