Presentation

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

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

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