Presentation

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

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

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