K379 is the locus of pivots of pKs meeting the circumcircle at the same points as pK(X6, X81). Its pivot is P as defined above and its isopivot is K. It is a member of the class CL043 : the tangents at the intersections with the circumcircle concur. It contains a large number of centers and the collinearities on the cubic are as follows : PX2X1169, PX4X1798, PX21X961, PX58X1220, PX81X2298, X2X4X21, X2X6X81, X2X961X1220, X6X58X572, X6X1169X1798, X6X1220X2298, X21X58X81, X21X1169X2298, X81X961X1798, X572X961X2298. It has the same asymptotic directions as pK(X6, X1211). Its isogonal and isotomic transforms are pK(X2092, X2) and pK(X1228, X76) respectively.
