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