Presentation

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

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

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

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