: In a French mathematical paper titled "Une nouvelle démonstration de la classification des feuilletages" , the term 67500x22x767500 x sub 2 squared x sub 7

: This research was part of a larger project called LATT (Large Aperture Telescope Technology) . Key Findings :

is part of a degree-5 homogeneous polynomial used to classify certain geometric structures (foliations) in complex projective planes. Project Name LATT (Large Aperture Telescope Technology) Primary Goal Ultra-lightweight, deployable mirrors for space Demonstrator Weight Total system mass of 2686g Source Publication Proc. SPIE Vol. 6750, 67500X (2007)

Researchers used a 400mm glass thin shell demonstrator with an areal density of approximately to prove the viability of deployable active mirrors.

: It identifies a 2007 paper titled "Deployable, lightweight and large aperture spaceborne telescope for LIDAR based earth observations".
