y z z

y z z (Libyan, Tifinagh, Twareg)
From this we see that Z leads to:
1) a combination of inverted and upright algiz that looks like a Tvimadur or a Wendehorn. This is effectively Algiz x 2
2) a doubling of this to form something reminiscent of a maltese cross. This is effectvely Algiz x 4.
3) an E form in different orientations. This is significant because in the so called Hands of God (Rece Boga), the Agiz x 4 principle becomes endowed with 4 E s. Another version becomes a Rune Compass. Alternatively we find an Algiz x 8 (cf. Vegvisier) 
4) a star form that is effectively the Hagal symbol.
