Let \(\overrightarrow{a}\) = 2î + ĵ - 2k̂ and \(\overrightarrow{b}\) = î + ĵ. If c is a vector such that \(\overrightarrow{a}.\overrightarrow{c} = |\overrightarrow{c}|, |\overrightarrow{c} - \overrightarrow{a}| = 2\sqrt{2}\) and the angle between \((\overrightarrow{a} × \overrightarrow{b})\) and \(\overrightarrow{c}\) is 30°, then \(|(\overrightarrow{a}×\overrightarrow{b})×\overrightarrow{c}|\) =
