Presentation

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

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

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

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