Presentation

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

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

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