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