Presentation

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

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

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