It is absolutely not. This has been addressed.
Never heard of the other coin sorry. The creators name of Isibeli is Isaiah and his wifes name is Bella and their childs name is Liam so its a combination of the 3 names and the triangles symbolise the 3 of them. The icon was inspired by a trinity icon which is available on google search. The trinity of the 3 family members as a tribute.
in relation to the white paper:
It is in reference to explaining what x11 algorithm in and also the project that it is forked from. Too many people are in erc20 ICO mentality. This is a free coin no ICO and no erc20 this is a forked coin uses reference information from the source which is completely acceptable.
