Presentation

minimal degreeμ(G) = 26
transitive degreeμt(G) = 256

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

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

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