Presentation

minimal degree	μ(G) = 28
transitive degree	μ_t(G) = 128

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

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