摘要翻译:
参考版本将出现在密歇根数学杂志上。前一版本最后一节中的一个错误已被更正。新标题准确地描述了所取得的主要结果。在三次曲面几何和Dolgachev定理的基础上,证明了本文所述模空间R的合理性。设M是平面上6个点的模空间,是三次曲面上由双六构型引起的自然对合的模。证明了R是以M为结尾的局部平凡射影丛的一个塔的双生的,从而证明了R的合理性是由Dolgachev定理得出的:M是有理的。

英文摘要:
Refereed version to appear in Michigan Mathematical Journal. A mistake in the last section of the previous version has been corrected. The new title exactly describes the main result obtained. Building on the geometry of cubic surfaces and on a theorem of Dolgachev, the rationality of the moduli space R mentioned in the title is proved. Let M be the moduli space of 6 points in the plane, modulo the natural involution induced by double-six configurations on cubic surfaces. It is proved that R is birational to a tower of locally trivial projective bundles ending onto M. The rationality of R then follows from Dolgachev's theorem that M is rational.
