Presentation

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

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

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

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