Part of an infinite series, where most tilings in this series are not flc, this one is the exception.
The reason is that the inflation factor is a - real - PV number.
By an argument in [PR] this forces flc.
Interestingly, the shape of the tiles can vary.
That is, there is one free parameter `$l$`

, `$0 < l < 1+s$`

, and the smallest prototile is the triangle with sides `$1,s,l$`

(`$s$`

the largest root of `$x^{3}-x-1$`

).
In particular, one can have obtuse triangles, as well as rectangular ones or acute ones as prototiles.
