In 1984, \textit{A. Ecker} and \textit{G. Poch} [Computing 37, 277-301 (1986; Zbl 0595.94012)] searched for TA-quasigroups, and they proved that there are no TA-quasigroups of order \(4k+2\). In fact they were not able to find TA-quasigroups for orders \(n=2,6\). In this paper the author supports to prove this conjecture to be wrong, except for \(n=2,6\), via the main Theorem: There are TA-quasigroups of order \(n\) for all \(n\neq 2,6\). On the other hand, in 2003 the author gave counterexamples to the conjecture of Ecker and Poch [\textit{M. Damm}, Computing 70, No. 4, 349-357 (2003; Zbl 1021.05016)].
