Presentation

minimal degree	μ(G) = 28
transitive degree	μ_t(G) = 64

A minimal faithful permutation representation — 3 generators on 28 points:

(2,3)(5,6)(7,9)(8,10)(11,12)(15,21)(18,25)(22,27)(26,28);(1,2)(3,4)(6,9)(10,11)(13,14,17,20)(15,18,22,26)(16,23,24,19)(21,25,27,28);(1,3,4,2)(6,10)(8,12)(9,11)(13,15)(14,18)(16,21)(17,22)(19,25)(20,26)(23,28)(24,27)
