Presentation

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

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

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