nL-e-L2 connects nL-e-P1 (Morley's EnnaDeltoid Center) and nL-n-P5 (Morley's 2nd Circle Center).
Let X be some point on (n-1)L-e-L2 with fixed ratio wrt nL-n-P4 and nL-o-P1. Then nL-o-L2 is the locus of the common intersection point of the perpendiculars through the n lower level versions of X to the omitted line preserving distance ratios.
In this way (n-1)L-e-P1 is transformed into nL-o-P1 and (n-1)L-n-P5 is transformed into nL-n-P4.
