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