Presentation

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

A minimal faithful permutation representation — 5 generators on 28 points:

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