... These are scalene triangles and each configuration has 2 different rotational combinations i.e. 6, 78 and 687, as in the preview case we can rotate through her Ai and we have in total 21 x 2 x 7 = 29 So total number of triangle containing 0 is 294 + 84 + 7 = 385 ...

On the regular elements in Zn
... In section 2, we characterize regular elements in Zn , the ring of integers modulo n, and find their von Neumann inverses. In section 3, a new arithmetic multiplicative function V (n), which counts the regular elements in Zn , is introduced. This new function is related to the famous Euler’s phifunct ...
