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