We determine that the maximum rank of an order-n tensor with format over the finite field is for even n, and for odd n. Since tensor rank is non-increasing upon taking field extensions, gives the largest rank attainable for this tensor format. We also determine a maximum rank canonical form and compute its orbit under the action of the symmetry group , and prove that this is the unique maximum rank canonical form, for even .

我们确定订单的最大等级-n 张量与格式 在有限域上 是 甚至ñ,和为奇数n。由于张量等级在进行场扩展时不会增加,给出此张量格式可获得的最大等级。我们还确定最大秩规范形式,并在对称群的作用下计算其轨道,并证明这是唯一的最大秩规范形式,即使 。
