Presentation

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

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

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