This applet draws a Hasse diagrams of Cobweb multi-blocks of the form Pk,n-k of layer <Φ1 → Φn> for the Natural numbers, Fibonacci and Gaussian integers. These blocks contain two blocks: Pk (red colors) and Pn-k (blue points) created by the recurrence rule of multi-F nomials coefficients for Cobweb Tiling sequences. We can think of it as a subsets Xs (|Xs| = k) of set N, such that red points (Pk) belong to Xs and blue points (rest of them) don't.
More information about multi-blocks, see On multi F-nomial coefficients [md7].
