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