There are 3 real forms: a compact one, a split one, and a third one. They are the isometry groups of the three real Albert algebras.
The F4 Lie algebra may be constructed by adding 16 generators transforming as a spinor to the 36-dimensional Lie algebra so(9), in analogy with the construction of E8.
In older books and papers, F4 is sometimes denoted by E4.
F4 is a paper format of size 210mm ×330mm (8.27in ×12.99in). Although metric, based on the A4 paper size, and named to suggest that it is part of the official ISO 216 paper sizes, it appears to be only a de facto standard.
It may be referred to as "foolscap" or "folio" because of its similarity to the traditional Foolscap folio size of 81⁄2 by 131⁄2 inches (215.9mm ×342.9mm).
(UPDATE) DRYX Saavedra rose to the occasion when it mattered the most ...FEU will make its sixth consecutive Final Four appearance dating back to Season 79 and is now eyeing to secure a twice-to-beat bonus with three matches left in the eliminations.
UE stayed winless at 0-10 to bomb out of semifinal contention since there are at least four teams with five wins ... Vhan Bangayan notched 13 points for UE ....
