  We demonstrate spontaneous spatial order in stripe and super-lattice solitons
in a Rashba spin-orbit (SO) coupled spin-1 uniform quasi-two-dimensional
(quasi-2D) ferromagnetic Bose-Einstein condensate. For weak SO coupling, the
solitons are of the $(- 1,0,+ 1)$ or $(0,+ 1,+ 2)$ type with intrinsic
vorticity, where the numbers in the parentheses denote angular momentum in spin
components $F_z=+1,0,-1$, respectively. For intermediate SO coupling, three
types of solitons are found: (a) circularly-asymmetric solitons, (b)
circularly-symmetric $(- 1,0,+ 1)$- and (c) $(0,+ 1,+ 2)$-type multi-ring
solitons maintaining the above-mentioned vortices in respective components. For
large SO coupling, quasi-degenerate stripe and super-lattice solitons are found
in addition to the circularly-asymmetric solitons. A super-lattice soliton
forms a 2D square lattice structure in the total density as in a super-solid;
in component densities it may have either (i) a 1D stripe pattern or (ii) a 2D
square lattice structure.
