Presentation

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

A minimal faithful permutation representation — 6 generators on 26 points:

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

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