Four octatiling: with stellaocti -1.2^8, -2.3^8, stellatetrus -1.3^4 with squares and spinners -2.3.1^4 and -3.3.2^4 in the gaps. All are topological truncated square tilings. 
More periodic octatilings
More octatilings - equilateral polygons, turn angles multiples of 45 degrees.
A little snake octatile, -2.3.2.1^2 self-tiles the plane with 2 orientation. It is topologically a hexagonal tiling, as shown right, by applying dual operation twice.
