A family of complex Hadamard matrices $D_{8}^{(4)}(a,b,c,d) = H_{8}\circ{\rm EXP}\left(i R_{D_8^{(4)}}(a,b,c,d)\right)$ found by P. Diţă [103]. It is stemming from $H_{8}$; $$H_{8}=\left[\begin{array}{rrrrrrrr} 1 & 1 & 1 & 1 & 1 & 1 & 1 & 1\\ 1 & 1 & -1 & 1 & -1 & -1 & 1 & -1\\ 1 & 1 & 1 & -1 & -1 & -1 & -1 & 1\\ 1 & -1 & 1 & 1 & -1 & 1 & -1 & -1\\ 1 & -1 & 1 & -1 & 1 & -1 & 1 & -1\\ 1 & -1 & -1 & 1 & 1 & -1 & -1 & 1\\ 1 & 1 & -1 & -1 & 1 & 1 & -1 & -1\\ 1 & -1 & -1 & -1 & -1 & 1 & 1 & 1 \end{array}\right], $$ where
$$R_{D_8^{(4)}}(a,b,c,d)= \left[\begin{array}{rrrrrrrr} \bullet & \bullet & \bullet & \bullet & \bullet & \bullet & \bullet & \bullet\\ \bullet & a+b & a & a & a+b & \bullet & b & b\\ \bullet & a & a+c & a & a+c & c & \bullet & c\\ \bullet & a & a & a+d & a+d & d & d & \bullet\\ \bullet & a & a & a+d & a+d & d & d & \bullet\\ \bullet & a+b & a & a & a+b & \bullet & b & b\\ \bullet & a & a+c & a & a+c & c & \bullet & c\\ \bullet & \bullet & \bullet & \bullet & \bullet & \bullet & \bullet & \bullet \end{array}\right].$$
