The mark consists of a design that resembles a TF. The T has the left portion of the crossbar removed and both designed letters have the same height. There is a narrow space between the T's stem and the F's stem equal to 1/10th the width of the F stem. The T has two arrows extending from it's stem pointing to the right passing through the F stem. The top arrow starts at the point corresponding to the middle of the space between the F arms; the arrow head height is the same as the space between the two F arms minus 1/5 the width of the F stem; the length of the arrow head is 9/7 the height of the arrow head; the arrow head's left side is right of the F stem by 1/10 of the F stem's width; the length of the arrow is such that it connects the stem of the T to the arrow head without spacing; and the arrow shaft thickness is half the space between the two F arms and has spacing around it equal to 1/10 the width of the F stem. The the second arrow has the same shape and is placed relative to the second F arm the same as the first arrow to the first F arm.
