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