Let BT4l denote a subclass of bounded turning functions connected with a four-leaf-type domain. The goal of the study is to probe into the bounds of coefficients |b6|,|b7|,|b8|, the bounds of the logarithmic coefficients, and the third-order determinants |H3,1|,|H3,2|,|H3,3| for the functions in this class.
