Presentation

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

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

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