Presentation

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

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

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