Presentation

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

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

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