Victims of Terrorist Attack on the Pentagon Memorial excluded from the burial so that there was no possibility that any terrorist remains were included. These terrorist and commingled remains were turned over to the Federal Bureau of Investigation (FBI) in February 2002. The FBI said the remains were "disposed of in a dignified manner'", although a very small amount of suspected terrorist remains were retained to aid in later criminal prosecutions. The Victims of Terrorist Attack on the Pentagon Memorial was dedicated on September 12, 2002. A funeral service for the 30 victims was held at the Arlington Memorial Amphitheater, the first time the amphitheater had held such
Heptagon in a circle of radius "R" is formula_5 while the area of the circle itself is formula_6 thus the regular heptagon fills approximately 0.8710 of its circumscribed circle. As 7 is a Pierpont prime but not a Fermat prime, the regular heptagon is not constructible with compass and straightedge but is constructible with a marked ruler and compass. This type of construction is called a neusis construction. It is also constructible with compass, straightedge and angle trisector. The impossibility of straightedge and compass construction follows from the observation that formula_7 is a zero of the irreducible cubic . Consequently, this
