Presentation

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

A minimal faithful permutation representation — 4 generators on 28 points:

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