Presentation

minimal degree	μ(G) = 28
transitive degree	μ_t(G) = 256

A minimal faithful permutation representation — 4 generators on 28 points:

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