Presentation

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

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

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