Für die von \textit{V. Boerner-Lantz} [J. Geom. 27, 112-118 (1986; Zbl 0604.12020)] angegebene Konstruktion endlicher distributiver Quasikörper (= semifield) wird die Anzahl der Isomorphietypen so erhaltbarer projektiver Ebenen vorgegebener Ordnung \(p^ 4\) bestimmt: Für \(p\equiv 1\bmod 4\) ist diese Anzahl \(1/4(p-1)\), für \(p\equiv 3\bmod 4\) ist sie \(1/4(p-3)\).

| selected citations These citations are derived from selected sources. This is an alternative to the "Influence" indicator, which also reflects the overall/total impact of an article in the research community at large, based on the underlying citation network (diachronically). | 0 | |
| popularity This indicator reflects the "current" impact/attention (the "hype") of an article in the research community at large, based on the underlying citation network. | Average | |
| influence This indicator reflects the overall/total impact of an article in the research community at large, based on the underlying citation network (diachronically). | Average | |
| impulse This indicator reflects the initial momentum of an article directly after its publication, based on the underlying citation network. | Average |
