Presentation

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

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

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