Presentation

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

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

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