Presentation

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

A minimal faithful permutation representation — 4 generators on 28 points:

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