Presentation

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

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

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