Presentation

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

A minimal faithful permutation representation — 6 generators on 28 points:

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