Presentation

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

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

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