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